Legacy speaks a language that I can understand. Simple.
I love the retro looks of the handheld and base styling but the key factor is the soft keys and the screen information. I can read the handheld and do not have to memorize key stroke to get what I want. Doing a multiple unit consist and creating it to run several locomotives at once is fun. For me with TMCC it was a chore to remember. I understand that some operators will remember the key strokes and overlays, but for me not always. I just have to look at the remote and it tells me what I am doing and I understand which buttons do which control.
In short, it makes me smile and forget about the world for just a small moment in time.
